ADJUSTABLE BEARING.

Application filed June 16, 1923. Serial No. 645,750.

To all whom 15 may concern:

Be it known that I, JosnrH E. Ronsnnnr, a citizen of the United States, residing at Sharon, in the county of Madera and State of California, have invented certain new and useful Improvements in Adjustable Bearings, of which the following is a specification.

' My invention relates to an improvement in adjustable bearings, particularly, but not specifically, adapted for the crank shafts of engines in the Ford type automobile, whereby the proper adjustment of the magneto of these engines may be maintained, it being of course well known that all four magnetos are part of the engin fly-wheel, and are adjusted by crank shaft bearings.

A further object of my invention resides in the provision of such an adjustable bearing that may be employed in lieu of the usual crank shaft bearings of the above type motor, for providing a means for more expeditiously adjusting crank shafts, my in-,

vention being additionally characterized by its simplicity, efficiency and durability, and one that may be manufactured and marketed at small cost.

The nature and advantages of the invention will be better understood when the following detailed description is read in con nection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein: c

Figure 1 is a fragmentary elevation of a Ford engine crank shaft supported by my improved adjustable bearing.

Figure 2 is an end elevation of the bearing cap, per se.

Figure 8 is an enlarged detail cross section of my bearing, and

Figure 4 is a fragmentary detail cross section of Figure 1.

Referring to the drawings 5 indicates the crank shaft of the Ford type engine, 6 the central crank portion thereof, 7 the usual bearing portion of the engine block having an arcuate-shaped lower end within which is engaged the said crank portion 6 of the shaft 5. 8 indicates the usual stud bolts carried by the said engine block and 9, the

locking nuts therefor. These elements are not of the essence of my invention, but are shown for permitting of the more adequate disclosure of my invention. I r

My invention, per se, embodies a cap plate 10, the top face of which is provided with a central, longitudinally extending arcuateshaped groove 11, for permitting of the positioning of the same upon the said crank portion 6 of the shaft 5, the ends of this plate adapted for close contact with the portion 7 of the engine block in a manner, clearly shown in the drawings.

Upon opposite sides of the said cap plate 10, the same is formed with projecting heads 12, which are formed with vertical oblong openings 13, for permitting of the engagement of said stud bolts 8 therethrough. Arranged perpendicularly to these oblong openings 13, and at one side of said heads 12, there is formed screw threaded openings 14, for the reception of set screws 15, the same adapted for engagement at their inner ends with the said stud bolts 8, for removing the cap plate 10, with respect to the said portion 7 of the engine block for thereby adjusting the crank shaft 5. Upon the said screw 15 are look nuts 16, for properly maintaining the bearing in its adjusted position.

It is, of course obvious that surrounding the crank portion f the shaft 5, and between the engine block and cap plate is the usual two-piece bearing sleeve 17 and in view of the above description, it is believed by me that it will at once be apparent to those skilled in the art that I have a highly improved form of adjustable bearing, and even though I have herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein, without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent, is:

1. In combination with the usual crank shaft-bearing portion of an engine block, wherein the same is provided with pendent stud bolts at opposite sides thereof, a cap plate positioned upon said crank shaft an in close engagement with the bearing portion of said engine block, said cap being provided with openings at the opposite sides thereof for the reception of said stud bolts,

and means for moving said cap plate in a longitudinal direction with respect to the bearing portion of said engine block.

2. In combination with the crank shaft bearing portion of an engine block and the engine crank shaft, a cap plate positioned upon said crank shaft, and in close engagement with said engine block bearing portion, said cap plate being provided With 0blong openings for receiving the usual pendent stud bolts of said engine block bearing portion, and means for adjusting said cap plate with respect to said engine block hearing portion.

3. In combination with the crank shaft bearing portionof an engine block and the engine crank shaft, a cap plate positioned upon said crank shaft, and in close engagement with said engine block bearing portion, said cap plate being provided With 0blong openings for receiving the usual pendent stud bolts of said engine block bearing portion, and means for adjusting said cap plate with respect to said engine block bearing portion, said means comprising set screws positioned Within openings at 0pp0- site sides of said cap plate and adapted for engagement with said pendent stud bolts.

In testimony whereof I affix my signature.

JOSEPH E. ROESBERY.
